So, I've been messing around with SteamVR on Apple Silicon and it runs as expected under Rosetta translation, I've even got a game to run. But for some reason SteamVR cannot detect a headset, even when using one that SteamVR has drivers for such as the 2017 Vive headset. Would there be any explanation as to why this is because SteamVR works as expected so that leads me to believe it's something with MacOS.

I am currently working on a project where I aim to overlay the camera feed obtained via the Apple Vision Pro's camera access API to align perfectly with the user's perspective in Vision Pro. However, I've noticed a discrepancy between the captured camera feed and the actual view from the user's perspective. My assumption is that this difference might be related to lens distortion correction or the lack thereof. Unfortunately, I'm not entirely sure how the camera feed is being corrected or processed. For the overlay, I'm using a typical 3D CG approach where a texture captured from the background plane is projected onto a surface. In this case, the "background capture" is the camera feed that I'm projecting. If anyone has insights or suggestions on how to align the camera feed with the user's perspective more accurately, any information would be greatly appreciated. Attached image shows what difference between the camera feed and actual user's perspective field of view. I want to align the camera feed image to the user's perspective.

I am creating a 3D model from multiple images using the photogrammetry session. Now, when the session generates an OBJ file and I measure the distance between two points, the distance is displayed sporadically in different units. Sometimes it's meters, then centimeters, or another unit altogether. How can I tell the photogrammetry session to always create the model in millimeters?

I tried to understand the view matrix. The part from original code as below: private func updateGameState() { /// Update any game state before rendering uniforms[0].projectionMatrix = projectionMatrix let rotationAxis = SIMD3<Float>(1, 1, 0) let modelMatrix = matrix4x4_rotation(radians: rotation, axis: rotationAxis) let viewMatrix = matrix4x4_translation(0.0, 0.0, -8.0) uniforms[0].modelViewMatrix = simd_mul(viewMatrix, modelMatrix) rotation += 0.01 } If the view matrix is initialed in x = -0.5, as:let viewMatrix = matrix4x4_translation(-0.5, 0.0, -8.0) The cube in the MetalView will move left. I think it should move to right hand side because View Matrix is camera position, am I wrong?

I have a 3х3 Matrix which I need to apply to UIImage and save it in Documents folder. I successfully converted the 3x3 Matrix (represented as [[Double]]) to CATrasform3D and then I have broken my head with trying to figure out how to apply it to UIImage. The only property where I can I apply it is UIView(or UIImageView in case with working with UIImage) transform property. But it has nothing to do with UIImage itself. I can't save the UIImage from transformed the UIImageView with all the transformations. And all the CoreGraphic methods (like concatenate for CGContext) only work with affine transformations which not suits for me. Please give me a hint what direction I should look. Does Apple has native methods or I have to use 3rd party frameworks for this functionality?

Hello, I'm writing to report an issue (or a documentation error). I am using the Entity/Component Architecture incorporated in the GamePlayKit framework. Additionally, I want to take advantage of the user interface provided by the Scene Editor. This is essential for me if I want to involve more people in the project. The issue occurs when linking the user interface data with the GKScene of the aforementioned framework. The first issue arises when adding a component through the interface as shown in the image Then at that moment: if let scene = GKScene(fileNamed: "GameScene") { // Get the SKScene from the loaded GKScene if let sceneNode = scene.rootNode as! GameScene? { Scene.rootNode is nil, and the scene is not presented. However, I can work around this issue by initializing the scene separately: if let scene = GKScene(fileNamed: "GameScene") { // Get the SKScene loaded separately if let sceneNode = SKScene(fileNamed: "GameScene") as! GameScene? { But from here, two issues arise: The node contains a component, and the scene has been loaded separately When trying to access a specific entity through its SKSpriteNode: self.node?.entity // Is nil It becomes very difficult to access a specific entity. When adding a component, an entity is automatically created. This is demonstrated here: The node contains a component, and the scene has been loaded separately. I only have one way to access this entity, and since there is only one, it's easy: sceneNode.entities[0] But even so, it's not very useful because when I try to access its components, it turns out they don't exist. I just wanted to mention this because it would be very helpful for me if this issue could be resolved. Thank you very much in advance.

I have tested my application in iOS 15, 16, 17 Version in that vision kit reading value in Horizontal direction once I got updated my device to iOS 18.0 beta value was reading as in vertical direction The build was generated in Xcode 13.4.1. Team please help to understand why this and need to change anything in code level

The following generates a prior definition warning from #include <__config>. But that has an ifndef in it. I'm in C++17 on Xcode latest (14.5). Is this documented anywhere? -D_LIBCPP_ENABLE_ASSERTIONS=1

I have a legacy app that draws using OpenGL, in particular is draws lines using glLineStipple. This is on a Macbook Pro M3, but it also happens on and x86 based Mac. This causes the following messages to be output to the terminal the app was run from: FALLBACK (log once): Fallback to SW vertex for line stipple FALLBACK (log once): Fallback to SW vertex processing, m_disable_code: 2000 FALLBACK (log once): Fallback to SW vertex processing in drawCore, m_disable_code: 2000 Is there a way of suppressing these messages?

I have a game for iOS where I use CADisplayLink to animate a simulation, and for some reason the animation is not getting the full 120hz on capable devices (like iPhone 15 Pro). When I enable a 120hz refresh target, the animation is capped at only 90hz. This looks terrible because the animation works best when doubled (30, 60, 120, 240, etc). The really bizarre thing is that when I turn on Screen Recording, my frame rate instantly jumps to 120, and everything looks perfectly smooth. My game has never looked better on iPhone! When recording is stopped, the animation drops back down to 90 fps. What in the world is going on? [displayLink setPreferredFrameRateRange:CAFrameRateRangeMake(100,240,120)]; //Min. Max, Preferred [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; (Also, CADisableMinimumFrameDurationOnPhone is set to True in info.plist)

Hi, I was wondering if we could ever get the Game Porting Toolkit to ever translate Vulkan and Vulkan RT extensions? The reason I ask is because I would like to try something involving RTX Remix which requires Vulkan specific extensions

I have been using the iOS 18 public beta on my iPhone XR for the past 3-4 days, and I frequently play a popular competitive game called “Free Fire.” I’ve noticed an issue while playing the game. Whenever I switch the game to the background for any reason, such as using another app or attending an incoming call, the game’s sound does not come back when I switch back to it. No matter what I do—whether switching the phone to silent mode and then back to normal or adjusting the volume—the sound won’t return. I have to restart the game, which is frustrating since I play this game a lot. I understand that this is a beta version, and some problems are expected, but I wanted to mention this issue here in case it can be resolved. and i also tried some stuff like reinstalling the game or restrting the device or checking for new updates and all the small stuff that would fix this but nahhhh none of them worked 😅

Does anyone know why the following call fails? CGPDFOperatorTableSetCallback(operatorTable, "ID", &callback); The PDF specification seems to indicate that ID is an operator? BTW what is the proper topic/subtopic for questions about Quartz? Wasn't sure what topic on the new forums to post this under.

I'm an iOS developer, and I've been testing our app in iOS 18.0 Beta. I noticed that there's a problem with the font rendering, and after troubleshooting, I've found out that it's caused by the removal of the PingFang.ttc font in 18.0. I would like to ask the reason for removing this font file and which font should be used to display Chinese in the future? My test device is an iPhone 11 Pro and the system version is iOS 18.0 (22A5297). I have also tested Beta 1 and it has the same issue. In previous versions of the system, the PingFang font is located in this directory /System/Library/Fonts/LanguageSupport/PingFang.ttc. But in iOS 18.0, the font file in this directory has become Kohinoor.ttc, and I've tested that this font can't display Chinese either. I traversed the following system font directories and could not find the PingFang.ttc font file. /System/Library/Fonts/AppFonts /System/Library/Fonts/Core /System/Library/Fonts/CoreAddition /System/Library/Fonts/CoreUI /System/Library/Fonts/LanguageSupport /System/Library/Fonts/UnicodeSupport /System/Library/Fonts/Watch Looking for answers, thanks for the help!

A sample of some error messages that are presented in the Xcode log for executon of a program. There is nothing in the messages that will help identify a component as the origin of the message, nor is there a locatable derinition for the various labels and fields of the text. What component or even framework does this set of messages originate? Your search engine is useless because it returns gibberish. It doesn’t even follow the common behavior of SEARCH ENGINES because it takes label strings compounded from common words and searches for the common word instead of using the catenated string that is the internal variable name that is in the text. 2024-06-22 19:45:58.089943-0500 RoomPlanExampleApp[733:30145] [ClientDonation] (+[PPSClientDonation isRegisteredSubsystem:category:]) Permission denied: GenerativeFunctionMetrics / ANEInferenceOperationPrepareForEncode.
